Operating system startup control method and information processing apparatus

Abstract

An operating system startup control method includes the steps of continuing an operation of a program loader for a specific processor among program loaders for the other processors that are started up by turning on of the power supply to the plural processors, while terminating the program loaders for the other processors; starting up an OS bridge that manages a hardware resource shared by the plural processor, using the program loader and starting up an operating system corresponding to the specific processor and another operating system corresponding to the other processors, using the OS bridge that is started up.

1. An operating system startup control method for starting an operating system processed by each of plural processors, the method comprising the steps of:
 continuing an operation of an initial program loader for a specific one of the plural processors among a plurality of initial program loaders that are started up upon turning on of power supply to the plural processors, while deactivating an operation of an initial program loader for another processor other than the specific processor; 
 starting up a managing program configured to manage a hardware resource shared by the plural processors, using the initial program loader for the specific processor; and 
 starting up an operating system corresponding to the specific processor and another operating system corresponding to the other processor using the managing program that is started up. 
 
     
     
       2. An information processing apparatus having plural processors for each of which an initial program loader is started up upon turning on of power supply,
 the plural processors including: 
 a specific processor for which an operation of the initial program loader that is started up is continued; and 
 another processor for which an operation of the initial program loader that is started up is deactivated, 
 wherein a managing program configured to manage a hardware resource shared by the plural processors is started up by the initial program loader for the specific processor, and 
 wherein an operating system corresponding to the specific processor and another operating system corresponding to the other processor are started up by the managing program that is started up.
